Description

Technical Field

[0001] This utility model relates to the field of temperature transmitter technology, specifically to a waterproof integrated temperature transmitter. Background Technology

[0002] Integrated temperature transmitters, with their advantage of integrating temperature sensors and signal conversion circuits, are widely used in industrial fields such as petrochemicals, power energy, and metallurgical manufacturing. They play a key role in converting physical quantities of temperature into standard electrical signals. In actual industrial scenarios, equipment often faces complex environments such as high temperature and humidity, which places stringent requirements on the waterproof sealing, heat dissipation performance, and environmental adaptability of integrated temperature transmitters.

[0003] Existing integrated temperature transmitters mostly use direct screw-on sealing of metal parts at their threaded interfaces, lacking a professional sealing structure design. During long-term use, gaps can appear at the metal threaded connections due to vibration and temperature changes, allowing external moisture to penetrate the equipment. Once moisture enters, it can cause short circuits in circuit boards, corrosion of electronic components, abnormal signal transmission, and even equipment malfunction. Therefore, there is an urgent need to design a waterproof integrated temperature transmitter to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof integrated temperature transmitter to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A waterproof integrated temperature transmitter includes a housing with external threads at both ends. A front cover and a rear cover are provided at each end of the housing. Two wiring holes are provided on the housing, one of which is threaded with a fixing mechanism. A threaded interface is provided at the bottom of the housing, and a temperature sensor is threaded into the threaded interface. A heat dissipation mechanism is provided on the outer wall at the bottom of the housing.

[0007] In a preferred embodiment of this utility model, both the front cover and the rear cover are provided with internal threads, which cooperate with external threads, and both the front cover and the rear cover are provided with sealing rubber rings.

[0008] In a preferred embodiment of this utility model, the fixing mechanism includes a threaded sleeve that is threaded into the wiring hole, a locking member inserted into the threaded sleeve, a rubber sleeve fitted inside the locking member, a locking cap threaded into the outer wall of one end of the threaded sleeve, and a waterproof ring provided between the threaded sleeve and the wiring hole.

[0009] In a preferred embodiment of this utility model, the heat dissipation mechanism includes a protective shell disposed at the bottom of the housing, an electric fan disposed on one side of the protective shell, a protective net disposed on one side of the electric fan, a dustproof net disposed between the protective net and the electric fan, an air outlet disposed on the outer wall of the other side of the protective shell, and a plurality of heat dissipation fins disposed on the outer wall of the threaded interface.

[0010] In a preferred embodiment of this utility model, one end of the temperature sensor is provided with a threaded connector, the threaded connector is threaded into the threaded interface, a sealing gasket is provided between the threaded connector and the threaded interface, and a fixing key is provided on the outer wall of the temperature sensor.

[0011] In a preferred embodiment of this utility model, the front cover is provided with an observation window, which is made of transparent glass.

[0012] In a preferred embodiment of this utility model, another of the wiring holes is threaded with a sealing bolt, and the waterproof ring is disposed between the sealing bolt and the wiring hole.

[0013] In the above technical solution, the waterproof integrated temperature transmitter provided by this utility model has the following advantages:

[0014] (1) By setting a sealing rubber ring, rubber sleeve and sealing gasket, a high elasticity and aging resistant rubber ring sealing structure is added at the threaded interface. The compression deformation characteristics of the rubber ring are used to fill the thread gap, which can effectively resist the intrusion of water vapor, dust and corrosive substances. By setting a fixing mechanism, the wire can be tightened and fixed. At the same time, the rubber sleeve can effectively ensure the sealing and prevent water from entering the housing along the wire.

[0015] (2) By setting up a heat dissipation device, the heat transmitted by the sensor is quickly dissipated to the outside, preventing the heat transmitted by the sensor from causing the housing temperature to rise, ensuring that the electronic components work within a safe temperature range, extending the service life of the temperature transmitter and ensuring measurement accuracy.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, the waterproof integrated temperature transmitter provided in this embodiment of the present invention includes a housing 1, both ends of which are provided with external threads 11. A front cover 2 and a rear cover 3 are respectively provided at both ends of the housing 1. Two wiring holes 4 are provided on the housing 1. A fixing mechanism 5 is threadedly engaged in one of the wiring holes 4. A threaded interface 12 is provided at the bottom of the housing 1. A temperature sensor 7 is engaged in the internal thread of the threaded interface 12. A heat dissipation mechanism 6 is provided on the outer wall at the bottom of the housing 1.

[0024] In this embodiment, external threads 11 are provided at both ends of the housing 1, and a front cover 2 and a rear cover 3 are provided at both ends of the housing 1 respectively;

[0025] Specifically, both the front cover 2 and the rear cover 3 are provided with internal threads 22, which cooperate with the external threads 11. Both the front cover 2 and the rear cover 3 are provided with sealing rubber rings 21. The rubber rings are made of fluororubber, which has excellent resistance to high and low temperatures and chemical corrosion. During installation, as the front cover 2 and the rear cover 3 are tightened, the sealing rubber rings 21 are uniformly compressed, which can form a solid sealing barrier at the connection between the housing 1 and the front cover 2 and the rear cover 3, effectively preventing the intrusion of external moisture, dust and corrosive gases.

[0026] In this embodiment, two wiring holes 4 are provided on the housing 1, and a fixing mechanism 5 is threadedly fitted on one of the wiring holes 4;

[0027] Specifically, the fixing mechanism 5 includes a threaded sleeve 51 that is threaded into the wiring hole 4. The threaded sleeve 51 is tightly screwed into the wiring hole 4 through the thread, while the waterproof ring 55 on the threaded sleeve 51 is squeezed, which enhances the airtightness between the threaded sleeve 51 and the wiring hole 4. This threaded connection method not only ensures the firmness of the installation, but also facilitates disassembly and maintenance. A locking element 53 is inserted into the threaded sleeve 51, and a rubber sleeve 54 is sleeved inside the locking element 53. The rubber sleeve 54 is made of high elastic silicone rubber, which can further enhance the wrapping and fixing effect of the wire, thereby improving the airtightness. A locking cap 52 is threaded into the outer wall of one end of the threaded sleeve 51. During the tightening process, it can apply axial pressure to the locking element 53 to strengthen the fixing effect of the wire. A waterproof ring 55 is provided between the threaded sleeve 51 and the wiring hole 4. The waterproof ring adopts a lip seal structure design. When subjected to pressure, the lip will tightly fit against the thread surface to form multiple sealing defenses to ensure the sealing at the wiring hole 4.

[0028] Specifically, another wiring hole 4 has a sealing bolt 10 threaded inward, and a waterproof ring 55 is placed between the sealing bolt 10 and the wiring hole 4. By tightening the sealing bolt 10, the waterproof ring 55 can be fully squeezed and deformed, thereby achieving a complete seal on the wiring hole 4 and effectively preventing external liquids and dust from entering the equipment.

[0029] In this embodiment, a heat dissipation mechanism 6 is provided on the lower outer wall of the housing 1. The heat dissipation mechanism 6 includes a protective shell 61 located at the bottom of the housing 1, which is made of aluminum alloy and has good thermal conductivity and mechanical strength. A fan 62 is provided on one side of the protective shell 61, and a protective net 63 is provided on the other side of the fan 62 to effectively prevent foreign objects from entering and ensure the normal operation of the fan 62. A dustproof net 64 is provided between the protective net 63 and the fan 62 to intercept tiny dust particles in the air and prevent dust accumulation from affecting the heat dissipation effect. An air outlet 65 is provided on the other outer wall of the protective shell 61. Several heat sinks 66 are provided on the outer wall of the threaded interface 12, which greatly increases the heat dissipation area and can quickly transfer the heat conducted by the temperature sensor 7 to the air. Combined with the forced convection heat dissipation of the fan 62, it effectively ensures that the internal electronic components operate within a safe operating temperature range and significantly extends the service life of the equipment.

[0030] In this embodiment, a threaded interface 12 is provided at the bottom of the housing 1, and a temperature sensor 7 is fitted into the internal thread of the threaded interface 12.

[0031] Specifically, one end of the temperature sensor 7 is provided with a threaded connector 71, which is threaded into the threaded interface 12. A sealing gasket 72 is provided between the threaded connector 71 and the threaded interface 12. When the threaded connector 71 and the threaded interface 12 are rotated together, the sealing gasket 72 is squeezed to seal the connection between the threaded connector 71 and the threaded interface 12, preventing external moisture from entering the housing 1. A fixing key 8 is provided on the outer wall of the temperature sensor 7. The fixing key 8 fixes the temperature transmitter at the position where temperature detection is required through threaded engagement.

[0032] In this embodiment, the front cover 2 is provided with an observation window 9, which is made of transparent glass. This glass not only has good light transmittance, allowing clear observation of the working status indicator lights and display screen information inside the equipment, but also has excellent impact resistance and scratch resistance. Even in harsh industrial environments, it can remain clear and transparent for a long time, making it easy for operators to monitor the equipment's operating status in real time.

[0033] Working steps: 1. Unscrew the back cover 3 to loosen the locking cap 52, then pass the wire from the fixing mechanism 5 and the wiring hole 4 into the housing 1, connect the wire through the back cover 3, then tighten the locking cap 52 to fix and seal the wire, put the back cover 3 on, and when the other wiring hole 4 is not connected to the wire, seal it with the sealing bolt 10 and the waterproof ring 55. Install and fix the integrated temperature transmitter to the position where the temperature needs to be detected through the fixing key 8, then open the front cover 2 for debugging, and close the front cover after completion;

[0034] Second, during operation, the temperature sensor is inside the heat source, and the heat will be transferred to the housing 1 along with the temperature sensor 7. When the fan 62 is turned on, the air is blown onto the heat sink 66, which can quickly dissipate heat and prevent the temperature of the housing 1 from rising.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
